It depends on which isotope you are asking about. Some decay through alpha, some decay through beta, some decay through other processes. All can leave the nucleus in an excited state, resulting in gamma emission.

alpha decay, beta decay, and gamma radiation
alpha, beta, gamma.
Alpha, beta, and gamma radiation were first observed from a sample of Radium in a magnetic field.
alpha decay, beta decay, and gamma radiation
gamma
Alpha decay decreases the atomic number by two. Beta- decay increases the atomic number by one. Beta+ decay decreases the atomic number by one. Gamma decay does not change the atomic number. However, gamma decay is often incidental to a precipitating alpha or beta event that upsets the energy equilibrium in the nucleus, so the two are not unrelated.
Beta or gamma disintegration.

Americium-241 has an alpha decay associated with gamma.
